In the drawings the device is seen as having two long angle-shaped elements 14 and i5. Slidably mounted on the upper extending legs of the angle shaped elements 14 and {5 is a hopper element 16. The hopper element I6 is provided with four short angle irons 11, l8; l9 and 28 which are securely fastened to the hopper elemerits IE with rivets 2 I. These four short angle irons l1, l8, l9 and 20 extend down and on the outside of the upper extending legs of the angle shaped elements l4 and I5 and permit the hopper It to slide along the top angle elements I4 and IE to any desired position. Securely fastened to the front lower eiitending legs of the angle elements I4 and I5 'are two plates 22 and 23. The lower ends of these two plates 22 and 23 are securely fastened (preferably riveted) to two long inverted 'L-shaped elements 24 and 25 which extend the full length 'of the niachine. Located in the approximate center of the two plates 22 and-23 is an elongated slot 26 and 21. The purpose of these slots 26 and '21 is to adiu'st'ably receive the ends of a pulley shaft 28. Welded to the front portions of the plates 22 and 23 and directly in l'iii with the slots 26 and 21 are two nuts 29 and '30 which threeeeaiy receive two adjusting screws 3| and 32. one end of these adjusting screws 3| and 32 is provided with a head 33 formed to receive a wrench for tightening or loosening purposes. The other ends of the adjusting screws 3| and 32 contact two hub elements 34 and 35. These two hub elements 34 and 35 fit over the ends of the shaft 28 and are provided with two locking screws 36 and 31. Inside of the hub elements 34 and 35 fit snugly against the inside hub of a pulley 38. The shaft 28 stands still and the pulley 36 revolves around the shaft 28 on two sets of roller bearings 39 and 49. The race for the bearings 39 and 49 are formed in the pulley 38. A packing gland 4| is positioned in front of the bearings 39 and 49 and a retainer ring 42 is positioned in front of the packing gland 4|.

At the rear of the machine and securely riveted to the upper angle l4 and extending down to and including the lower inverted L-shaped element 24 and riveted securely thereto and then on down to support the axle 43 is a plate 44. At the center of the plate 44 is located a slot 45 through which a drive shaft 46 extends. The shaft 46 xtends through two retaining washers 41 and 48 and on into a conventional ball bearing element 49 that is supported in an adjustable bearing case 59. The adjustable bearing case 59 is held in place by two bolts and 52 mounted on the front portion of the plate 44 and squarely in front of the bearing case 59 is located and securely welded thereto, a nut 53 with a long adjusting screw 54, threaded therethrough one end of the adjusting screw 54 comes into contact with the foot formation 55 that is an integrally formed part of the adjustable bearing case 56.

Securely fastened to the shaft 46 by means of four set screws 56, 51, 58 and 59 is a driving pulley 69. The shaft 46 extends on through a hole 6| in another plate 62 which is securely riveted to the top angle l4 and extends downwardly to and including the lower inverted L-shaped element 24 and is riveted securely thereto and then extends on down to support the other end of the axle 43. The axle 43 supports one on each end thereof, two wheels 63 and 64. Located on the outside of the plate 62 is a gear box 65 which has a removable side 66 which is held in place by bolts 91. The shaft 46 extends into the case 65 and through a conventional ball bearing 68 that is held in place by a bearing socket 69 which is formed as a part of the case 65. The shaft 46 extends on through a spacer l9 and into a gear 1|. A half moon key 12 keeps the gear H from turning on the shaft 46. The shaft 46 then extends on into a second ball bearing 13 that is held in place by a bearing socket 74 that is an integrally formed part of the removable side plate 66. Up toward the top of the removable side plate 66 is located a V belt pulley 14' that is fastened to the shaft 13 by a half moon key 15. The shaft 13' then extends through the removable side plate 56 and into a ball bearing l6 which is held in a bearing socket 11 which is an integrally formed part of the removable side plate 66. The shaft 13' then extends through a washer or spacer l8 and into another gear 19 that is held in constant mesh with the larger gear H. The shaft 13 is securely fastened to the gear 19 by a half moon key 89 and then the shaft 13 extends through a second washer or spacer 8|, then into a second ball bearing 82 which is held in a bearing socket 83 which is an integrally formed part of the case 65.

Located-in the rear of the two side'plates 44 and 62, directly below and to the rear of the two long inverted L-shaped elements 24 and 25 is positioned a motor support rod 84, one end of which is fastened to the side plate 44 and the other end of the motor support rod 84 is fastened to the side plate 52. The motor 85 is provided with a V belt pulley B6 and a V belt 81 is placed thereon and extends to and around the V belt pulley 14. The motor 85 is mounted on a motor support plate 88. The forward portion of the motor support plate 88 is provided with two hook elements 89 and 96 that easily hook over the motor support rod 84 or easily unhook from the motor support rod 84. The weight of the motor 65 which is mounted on the motor support plate 88 at all times keeps the V belt 81 tight on the two V belt pulleys 86 and 14' by the hinge connection of the hook elements 89 on the support plate 88 which is rigidly held between the two side plates 44 and 62.

Located on both of the sides l4 and i5 under the conveyor belt 9| and also on the bottom is riveted a plurality of rectangular shaped support elements 92. A long strip of metal 93 is welded securely to the under side of the two long inverted L shaped elements 24 and 25. This metal strip 93 is further support for the conveyor belt 9| and also a reinforcement for the entire machine. At the rear of the machine and extending a short distance toward the front and directly in front of the rear drive pulley is a strip of metal 94. This metal strip 94 serves as a'rear support for the conveyor belt 9| and also a reinforcement for the rear portion of the machine. Directly in front of the metal strip 94 is located an open space 95. A hood element 96 is located directly under the open space 95. This hood element 99 serves as a dispenser for the coal dust and deflects the dust away from the machine onto the ground or any satisfactory means for catching the dust.

The operation of the device is as follows. The front end of the machine can be raised and the machine towed behind a truck or due to the eX- treme absence of weight the machine can easily be loaded on a truck and hauled to the work. Upon reaching the work the machine is placed in the desired spot for unloading the coal. Then the forward end of the machine is shoved into the window or coal opening of thebuilding. The motor is then unloaded and the hooks 89 on the motor support bar 88 are hooked on the motor support bar 84. Then the V belt 81 is placed around the two pulleys 85 and 14 and the motor 85 is allowed to support itself. The weight of the motor 85 keeps the belt 81 tight at all times. Then the conveyor belt 9| is checked for tightness. If the conveyor belt 9| is too tight or too loose the required adjustment can easily and quickly be made by the two adjusting screws 3| and 32 which force the two hub elements 34 and 35 away from them and against the pressure of the conveyor belt 9| to tighten or let the hub elements 34 and 35 slip back with the pressure of the conveyor belt 9| to loosen as the case may be. At the rear end of the machine the adjusting bolt 54 may be turned to force the foot 55 of the bearing support element forward or permit it to move rearwardly as the need may be. The purpose of this adjustment is to compel the conveyor belt 9 l 1torun at the proper position on the driving pulley 69." By thiswe mean, not too close to one side or the other, which would cause excessive wear on the conveyor belt 9|. The motor 85 is then started which turns the V belt pulley 86 and drives the v belt 81 which in turn revolves the second V belt pulley l4 and the shaft 73 is revolved within the bearings 16 and 82 to revolve the gear 19 which is in mesh with a second gear 1|. As the gear H is revolved, the shaft 46 is also revolved in the bearings 49, 68 and 13. As the shaft 46 is revolved, the pulley 60, which is locked onto the shaft 46 by the four set screws 56, 51, 58 and 59 is also revolved to drive the conveyor belt 9| down and around the front pulley 38 which is revolvably mounted on bearings 39 and G0 and the shaft 28 to carry the coal into the bin.

The hopper 16 can be moved in the desired position on the machine for the truck to dump the coal into the coal conveyor.
